96 CiEO. IT. HORN, M. I). 



S. Phelpsii Crotch.— Oval, outline nearly coTitinuous, very little longer 

 than wide, moderately convex, rufo-testaceous. underside never entirely black. 

 Head and thorax spar.sely puncfcite, the latter narrower in front, sides feebly 

 arcuate, basal marginal line indistinct. Elytra moderately, not closely punctate, 

 the punctures coarser and finer intermixed ; prosternum narrower in front, a fine 

 elevated line each side ; metasternum closely puru^tate at sides, mesocoxal line 

 curved, joining the suture behind the apex. Abdomen less closely punctate, the 

 metacoxal line arcuate close to the suture, incomplete externally. Legs rufo- 

 testaceous. Length .08 inch. ; 2 mm. 



The ine.'^osternuui is always piceous, the ahdoinen may he piceous, 

 except at ape.v, or luay he entirely pale. 



Tliis species reseinhles iirbulo-'<i(.'<, hut the two differ in the meta- 

 coxal arc. Here it approaches within a fifth of the length of the 

 segment to the first suture, and in nehuloxn'^ is one-third from the 

 suture. The ahdomen is similarly formed in the two species. 



Hdb. — British ('oluml)ia, Oregon, northern California and Nev. 



S. oir<*iiinspec'tiis n. sp. — Bioadly oval, convex, black, each elytron with 

 an oval orange spot, in front of middle, placed slightly obliquely, the outerside 

 truncate. Head moderately closely punctate. Thorax narrowed in front, sides 

 moderately arcuate, di.sc rather closely not coarsely punctate, basal marginal line 

 distinct. Elytra rather coarsely punctate, closely but not densely ; pro.sternum 

 punctate, with elevated, convergent lines; metasternum closely punctate at the 

 sides, mesocoxal line arcuate. Joining the suture near the front. Abdomen closely 

 punctate, metacoxal line arcuate, not reaching the suture, incomplete externally : 

 femora piceous, tibiie and tarsi yellow. Length .10 inch. ; 2.5 mm. PI. II, fig. 4. 

 The abdomen has five segments. This species is easily known, 

 being the only one in our fauna with the incomplete, but arcuate 

 metacoxal line having an elytral spot. 



Huh. — Lookout Mountain, Tenn., Louisiana (Ulke). 



S. opaculU!i n. sp. — (Jval, convex, very little longer than wide, margin 

 continuous, piceous, head and sides of thorax broadly yellow, elytra with an 

 apical pah^ space occupying a fourth, the anterior edge on each side convex in 

 front. Head sparsely ])unctate. Thorax narrower in front, sides arcuate, disc 

 sparsely finely punctate, liasal marginal line indistinct. Elytra moderately closely 

 and more coarsely punctate than the thorax: prosternum punctate, the lateral 

 elevated lines indistinct ; metasternum coarsely and closely punctate at the sides, 

 the Tiiesocoxal line joining the suture a little in front of the middle. Abdomen 

 yellow at sides and apex, composed of five segments. clo.sely punctate, the meta- 

 coxal line touches the suture and curves feebly forward. Legs yellow. Length 

 .10 inch. ; 2.5 mm. 



This species has consideralile superficial re.semblance to Brullei, 

 but is darker, differing especially in the form of the metacoxal line, 

 which is a complete arc in Brullei. There is a distinct epipleural 

 fovea for the reception of the knee of the middle leg.
